Build a portable change-contract system for any repository. Use when creating or porting a repository workflow based on tracked feature records, lifecycle directories, a policy file, a checker, a lifecycle transition helper, and aligned docs/tests.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Development Contract System Use this skill when a repository needs a deterministic, reviewable workflow for tracking substantive work through repo-owned feature records instead of ad hoc notes. This skill is self-contained on purpose so it can be moved into another repo or skill collection without depending on the smaller contract skills from this frame at runtime. When the target repo uses local skills, generate a thin overlay with its concrete policy and helper commands. Reference `development-contract-process` only when the target agent has that skill; otherwise include the minimum operator flow. Build or port the system only within the requested scope. Review and design requests return findings or a draft without creating policy, records, helpers, or new enforcement. Preserve an existing system until its migration is explicit. ## What this skill builds A complete repository-local contract system with these parts: - a repo-owned policy file - a `feature_records/` directory with lifecycle subdirectories - a Markdown template for new records - a root `feature_records/README.md` - a checker script that validates record structure and changed-path coverage …

How to install
mdr add n-n-code/n-n-code-skills/development-contract-system@sha256:ffb982033fdc680eThe line at the top of this page pins the label git:20260904.6c1f699, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
